Answer:
Because the link between behavioral health and mental health varies from patient to patient
Explanation:
The link between behavioral health and mental health may vary depending on the person and therefore this association should be analyzed case by case. For instance, a patient with chronic conditions or who is injured in an accident may also be depressed. However, another patient who is depressed may have no physical signs of injury. Nonetheless, it is important to note that many mental disorders have a strong association with biological conditions and they can be modified by suitable treatments (e.g., drugs to correct abnormal expression of neurotransmitters), while there are other conditions that currently have no treatment option (e.g., mental disorders associated with genetic factors).
